ELECTRICAL DISTRIBUTING CABINET.

Application filed June 15,

To all whom it may concern Be it known that I, ALBERT E. BLACK- .uxx. acitizen of the United States. residing at Mount. Vernon, New York city,New

York, have invented certain new and useful switches, panel boards andthe like, and

which is made up of one or more detachable units so as to be extended toany desired size.

My object is to provide an economical and simple construction of such acabinet, and for this purpose the parts are preferably 'niade of sheetmetal stamped out and bent into shape. and having formed integrallytherewith as much of the parts of the cabinet as is possible.

My invention will be defined in the claims. cm the drawings which showthe. preferred embodiment of my invention, Figure 1 is a lrm ritudinalsection of the box made up from three units and with tlie'lid raised:Fig. 2 is a side elevation of the same with the id closed; Fig. 3 is atransverse section through 3--3 of Fig. 2 showing the lid in raisedposition; and Fig. 4 is a detail section through line 4-4 of Fig. 2.

. Since the units or sections which make up my box are exactly similarand interchangeable, a description of any one w ll sufiice.

1 indicates a body section formed of sheet metal stamped out and withsides bent upwardly as shown. The ends of such a body section are open,and are provided along their border with bolt holes indicated at 15,whereby they may have attached thereto either an end wall 3 or anauxiliary member 2, which I call a strap union, for joining two saidadjacent body sections together. The strap member 2 as shown issimilarly beat up at the sides and is coincident with the body sectionsthroughout. The end wall 3 is provided with vertically-disposcd inturncdflanges 13 and a horizontally-dis posed inturned flange 14 as shown, andboth the flanges of these end walls 3 and the bordering edges of thestrap union 2 are provided with bolt holes similarly disposed so as vtomatch the bolt holes at the adjacent:

edges of the-body section 1, whereby the end wall 3 and the strap union2 may be in terchanged. The sides of the body section are provided withknock-out plugs 11 Patented Aug. 20, 1912.

formed in the usual manner, and the end walls 3 are likewise providedwith such knockout plugs 12, whereby connections may be introduced tothe interior of the box.

One side wall of each body section 1 has preferably. formed integrallyat its upper end turned-over hinge loops 5, and a cover section 4 (onefor each body section) has similarly formed hinge loops 6, whereby a rod7 may be inserted through the hinge loops 5 and 6 to suitably hinge thecover sections and the body sections together. Running across all ofthe. cover sections 4 and connected thereto by suitable bolts is anangle bar 8, which serves tohold said cover sections together and form acommon lid for the entire box. Spaced apart along this angle bar 8 aresuitable weakening notches 9, whereby said bar may be easily broken tolit the length of lid for which it is designed. It is understood thatthe units may be built through the bolt holes as shown, and that theangle bar 8 employed to connect the cover sections is broken off for theright length. The notches 9 preferably are arting edges of two coversections, whereby the connecting bar 8 will not be weakened at thesepoints. i

The bolts shown as connectingthe bar 8 to the cover sections 4 at 10 maybe interchanged at any desired point witha handle .knob 16 as shown inFig. 4. In thiscase the handle knob 16 has a reduced end extendingthrough the cover section and the shown, whereby it serves to hold allof these parts together. each body section adjacent this knob 16. andbolt 10 is formed with a slight depression'in which the latch member 17may spring and by frictional engagement therewith hold the lid closed.

Various modifications may be made in the detailed construct-ion of myinvention with out departing from the spirit thereof as defined in theappended claims.

of the cover sections 4 are beveled in the same direction at 19 in orderto provide a closer union between said sections, and prevent gapping orany separation of the same.

I claim: 1. An out-let box comprising in combination one or more bodysections, a strap-union The front wall of It is to be noted that theabutting edges up to form any size box by suitable bolts 7 ranged so asnot to come opposite the rabutangle bar 8, and a latch member 17 as"between adjacent body sections, said body sections and strap-union beingprovided with matched bolt holes for connecting two of such sectionstogether, detachable end walls having inturned flanges similarlyprovided with bolt holes so as to be interchangeable with saidstrap-union, a separate cover section hinged to each body section and across-bar connected to and holding together all of said cover sectionsto provide a common lid for said entire box.

2. An outlet box comprising in combina tion one or more body sections, astrapunion between adjacent body sections, said body sections andstrap-union being pro- .vided with matched bolt holes for connecting twoof such sections together, detachable end walls having intnrned flangessimilarly provided with bolt holes so as to be interchangeable with saidstrap-union, a separate cover section hin ed to each body section and across-bar 0 angle iron having weakening notches at intervals thereon,

said cross-bar being connected to and hold-' ing together all of saidcover sect-ions to provide a common lid for said entire box.

3. An outlet box comprising one or more body sections formed of stampedmetal turned up at the sides with knock-out plugs in said sides, astrap-union bet-ween adjacent body sections, said body sections andstrap-union being provided with matched bolt holes for connecting two ofsaid body sections together, detachable end walls with knock-out plugstherein having inturned flanges similarly provided with bolt holes so asto beinterchangeable with strapunions,'a, separate cover section formedof stamped metal hinged to each body section, and a cross-barconnectedto and holding together all of said cover sections to provide a lid forsaid entire box.

4. An outlet box comprising in combination one'or'more body sectionsformed of stainped metal turned up at the sides with knock-out plugs insaid. sides, a strap-union between adjacent body sections similarly bentup at its sides and coincident with the bottom and sides of said bodysections, said body sections and strap-union being provided with matchedbolt holes for connecting two of said body sections together, de-

changeable with said strap-union, a sepa rate cover section formed ofstamped metal hinged to each body section, and a cros bar connected toand holding together all similarly provided with bolt holes so as to beinterchangeable with said strap-union, a separate cover section for eachbody section having an integral hinged loop thereon, a single rodpassing through the hinged loops of said cover sections, and said bodysections, and a cross-bar connected to and holding together all of saidcover sections to provide a common lid for said entire box.

6. An outlet box, comprising a plurality of body sections, and astrap-union between adjacent sections .and which is bent up at its sidesand extends along the bottom and sides of said body sections in adirection transverse of the box, said body sections and strap-unionbeing provided with matched holes to receive fastenings forconnectingthe same together, a cover section for each body section, and a crossbar connected with and holding said cover sections together to provide acommon lid for said entire box.

7. A lid for an outletbox, the same com- ALBERT E. BLACKMAN.
